Application filed July 23, 1914. Serial No. 852,729.

To all whom it may concern Be it known that I, 01.01 FROBERG, a citizen of the United States, residing at Benton Harbor, in the county of Berrien and State of Michigan, have invented new and useful Improvements in Collar? and Gulf Starchers, of which the following is a ing with the other, and at the same time working with a high efliciency.

A further object is to give a desirable conveying and delivering mechanism for handling collars, which will enable the tending of the machine as to the feeding and removal of collars and cuffs by one operator, with a minimum number of movements.

A purpose also is to present eflicient means for insuring the proper entry of starch into the body of collars and cuffs, operative to remove excess of starch, and adjustable to meet the conditions of various grades of starch,that is, thick, or thin, high grade or low grade.

It is an aim of the invention to enable the same starch pan to be used both for shirts and to supply the starch for collors and cuffs, when desired.

Additional objects, advantages and features of invention will appear, some of which will be at once apparent from the following description of the peculiar construction arrangement and combination of parts in the present embodiment of my invention, in the drawings of which Figure 1 is a side view of the invention, Fig. 2 is a front view thereof, Fig. 3 is a sectional view, Fig. 4 is a transverse sectional detail showing the mounting and adjustment of the arm 35' and roller 85. Fig. 5 is a detail of means for lifting the roller 22.

There is illustrated a suitably mounted starch box 10 with a steam chest 11 of ordinary construction in the lower part, and provided with the drain cook 12. At one side of the box there is mounted in a suitable manner the drive shaft 13 carrying the loose and splined pulleys 14 and 15 receiving alternately the power belt 16, the shifting means for which is not shown and may be of any familiar form. This shaft carries a small gear 17 meshed with two large gears 18 and 19, the former being carried on a stub shaft 20 mounted on the side of the box 10. while the second large gear is carried by the shaft 21, journaled on the upper edges of the box and extending transversely thereacross near the front. On this shaft there is splined the large roller 22 the periphery of which is spaced suitably from the adjacent end of the box to admit a small roller 28, with a clearance between the rollers, the latter roller being journaled in slots 24: formed in the edge of the box at each side. At each side of the box adjacent the inner side of the large roller there are standards 25, extending some distance above the roller and having horizontal arms 26 extended forwardly above the roller, stopping short of a vertical line from the front end of the box 10. The arms 26 carry at their outer ends the transverse apron roller 27. At the upper ends of the standards 25 there are vertical. slotted guide brackets 28, in

each of' which there is vertically movable the journal box 29 adjustable by the hand screw 80 threaded into the upper end of the bracket. In these boxes 29 there is journaled the adjusting roller 31. Immediately below these brackets slots 32 are formed in the rear sides of the standards inclined downwardly toward their inner ends, and journaled in the slots there is a roller 33,

the upper side of which is approximately on the level with the under side of the roller 27.

A transverse rod 34: is mounted across the box just below the roller 23, upon which are pivoted the outer ends of L-shaped arms 35, extending inwardly and downwardly be ncath the large roller and thence upwardly, being provided with interiorly threaded blocks 36 at their upper ends located over' the sides of the box, through which are engaged the adjusting screws 37 bearing downwardly upon wear plates 38 on the box. The lower ends of the arms are horizontally slotted as at 39, to allow limited movement on the rod. The lower portions of the arms 35 are formed with slots 40 opening upwardly, in which there are journaled two rollers 41, spaced a suitable distance apart and adapted to bear simultaneously against the large roller under adjustment of the screw 37. A third roller 4]. is mounted in suitable horizontal slots opening at the rearmost lower portion of the arms 35, located approximately in 'a vertical line with the roller 31 at the upper ends of the standards. An endless apron belt 42 is engaged outwardly of the rollers 27, 29, 41, 41 and 23, extending under the large roller 22 and in wardly of the roller 33. A multiplicity of laterally spaced endless tapes 43 are engaged around the large roller and the roller 33, the tapes and apron being thus adapted to move together from the throat or receiving space 44 between the rollers 22 and 23, to the roller 33. Carried by the arms 26 at the left and right sides respectively, there are brackets 45 and 46, the latter having suitable bearings 47' immediately below the level of the apron passing from the roller 33 to the roller-27. Two of the respective brackets are on each arm, the first named brackets being .slotted and having sliding journals 48 adjustable by screws 49 threaded into the brackets as shown. In the j ournals 47 and 48 rollers 50 are mounted, on which an endless delivery apron 51 is stretched, the inner edge of which is closely adjacent the rcller33, whereby it may receive collars and'cuft's passing over the last named roller. The right hand roller 50 (Fig. is carried by a shaft 52, at the inner end of whichthere is secured a bevel gear 53 meshed with a larger bevel gear 54 at the end of a shaft 55, which may be the support for the roller 33. The roller 50 at the left is located well outwardly of the arm 26 so that articles falling thereover will pass clear of the roller 22, and land upon theside table 56, the movement of the apron 51 being toward the left in its upper reach. If desirable, a small sprocket 57 may be mountedon the shaft 55 and driven by a large sprocket 58 and chain 59, the large sprocket being on the shaft of the large roller, as shown. 1

Mounted on the upper edge of the box spaced from the standards 25 oppositely from the large roller there is a crank shaft 60 carrying a gear 61 meshed with the gear 18. ()utwardly of this shaft there is a roller 61, mounted upon the shaft 62 which suspends a dasher board 63, connected by the link 64 to the crank 65 of the shaft 60, be fore mentioned. A shirt table piece 66 is mounted slidably upon the box outwardly of the roller 61 and is provided with a pivoted board 67 similar to and opposed to the v one 63, the adjacent faces of these boards ing against the board and mounted on the end of the box 10. The mounting of the roller 61 consists of a suitably slotted guide block 69, in which a slide bearing 70 is mounted, carrying the roller shaft, a spring 71 being engaged in the inner end of the slot to hold the roller yieldably at the outer limit of its movement. The upper end of the board 67 is concaved so as to snugly fit against the roller when pressed inwardly under sliding movement of the table (ill. The sliding movement of the table (36 is con-- trolled by the foot pedal 7 2, pivoted on the supporting frame work of the box 10 connected by any suitable operative connections with the table, for inward movement thereof. In the present case, a cable 73 at each side of the device is connected to the under side of the table within the box 10, from whence it extends outuuirdly through an opening 75 in the side of the box around a suitable pulley 74, shown in'ldig. 1. From here the cable is carried outwardly again and over a suitable pulley 76, where it is connected through the agency of a spring 77 and rod 78 to the foot pedal.

It should be noted that the upper portion 80 of each arm 35 has an intermediate ofi'set portion 31, whereby to accommodate diagonally arranged guides 82 secured to the box 10 at each side adjacent the upper edge, each guide having a sliding bearing 83, adjustable by a screw 84 projected above the box. The bearings 83 support a supplementary starch expressing roller 85, which may be caused to press with considerable force against the large roller 22 adjacent the top of the box, the guideway 82 being disposed at an acute angle to the periphery of the roller 22 so that the maximum pressure is attained with a minimum of effort on the part of the operator. Sufiicient play of the shaft of the roller 85 must of course be permitted in the arms to prevent interference with their separate adjustment.

In operation, the box being filled to the proper depth with fluid starch, and power being communicated through the belt 16, the roller 22 will rotate in a counter clockwise direction as viewed in Fig. 4. Collars and cuffs may then be fed to the throat 44, and will be carried beneath the roller in close contact with the apron 43 which will have previously circulated through and taken up a large quantity of starch. As the rollers 41 are encountered the starch will be pressed through the fabric of the collars and cuffs and surplusage removed. This removal of starch may be made more thorough by adjustment of the roller 85, although the pressure of the rollers 41 may be modulated by the adjusting screw 37. The collars and cuffs are carried past the roller 22 upwardly by the apron and tapes, and discharged upon the delivery apron 51, by which they are carried to the left side of the machine and dropped upon the table 56. In case the cuifs and collars tend to adhere to the apron, a series of spring fingers 87 may be mounted between the outer brackets 15 and l6, whereby the adhering articles are loosened and caused to fall upon the delivery apron. The delivered cuffs and collars may be brushed from the table 56 into a receptacle by the same operator who feeds the machine, or a receptacle, such as a basket, may be set upon the table to receive the articles direct.

For starching shirts, the table 66 is drawn outwardly, presenting a space between the boards 63 and 67 before the roller 61, through which the garments are dropped as far as desired. The table 66 is then pressed inwardly with the necessary force, which may be readily accomplished by a slight pressure on the pedal 72 and the garment withdrawn while pressure is maintained on the pedal, the upper part of the board 67 and the roller 61 cooperating to express the surplus starch.

For convenience in cleaning out the starch box, there may be provided at each side a lever 90, as shown in Fig. 5 pivoted intermediately of its length upon the end of the shaft 23, the lever extending inwardly and having a recessed inner end 91 receiving the shaft 21 therein, whereby when the bearings of the shaft are loosened, the levers may be depressed at their outer ends to lift the rollers 22 out of the box, enabling ready access to the interior thereof.

It will be noted that the connections with the transverse conveyer are such as to make it operate more rapidly than the apron belt, whereby articles are kept separated and delivered one at a time under the customary method of feeding.
